Given numbers are 991,293,440,861,697
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,293,440,861,697 is 1870019021640.
Find LCM of 991,293,440,861,697 with Prime Factorization
41 | 991, 293, 440, 861, 697 |
991, 293, 440, 21, 17 |
Multiply the prime numbers at the bottom and the left side.
41 x 991 x 293 x 440 x 21 x 17 = 1870019021640
Therefore, the lowest common multiple of 991,293,440,861,697 is 1870019021640.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
991 x 293 x 440 x 861 x 697 = 76670779887240
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
991 : 1, 991
293 : 1, 293
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
861 : 1, 3, 7, 21, 41, 123, 287, 861
697 : 1, 17, 41, 697
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,293,440,861,697, is 1.
Now, the common factors can be found like this.
991:991
293:293
440:2x 2x 2x 5x 11
861:3x 7x 41
697:17x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
41 = 41
Therefore, the value for common factors is 41.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 76670779887240/(1x41)
LCM = 76670779887240/41
LCM = 1870019021640
Thus, we can understand that the LCM of 991,293,440,861,697 is 1870019021640.
